PACKAGING Filed June 27, 1950 2,777,770 Patented Jan. 15, 1957 2,777,770 PACKAGING Guy Norwood Fisher, Wilmette, 112., assignor to Kraft Foods Company, Chicago, 111., a corporation of Delaware Application June 27, 1950, Serial No. 170,649 3 Claims. (Cl. 99-178) The envelope is then sealed and the entire assemblage consisting of the mold, envelope, and the cheese product and the packaged cheese unit is then removed from the mold. A number of the Wedge-shaped units of cheese product are then placed in a suitable carton for shipping.

While the Wedge-shaped form of package has distinct advantages from the standpoint of sales promotion, it is Moreover, the removal of the envelope of cooled cheese product from the mold and the packaging of the number of cheese units in the shipping cartons is likely to damage the envelopes so as to impair the keeping quality of the cheese and so as to distort the unit. In addition,

the finished packaged unit.

Accordingly, the principal object of the invention is the provision of an improved method of packaging plastic the accompanying drawings.

In the drawings:

Fig. 1 is a fragmentary, perspective view of an improved container for wedge-shaped units, embodying various features of the invention. This view shows the man ner in which the individual wedge-shaped units are dis posed within the container;

Fig. 2 is a perspective view of a superposed pair of liner part of the assembled shipping carton illustrated in Fig. l, the wedge-shaped units being removed for purposes of clarity;

In general, a package embodying various of the features of the invention liner member to various plastic the carton. At vided a right 21 as indicated at 23 in Fig. 3. liner 7, the rectangular panels 17 and 19 are folded together along their common side 20 to provide a V-shaped trough and the triangular end panels 21 are folded in wardly to provide ends for the trough as shown in Fig. 4.

To facilitate the removal of the packaged cheese from the liners after it reaches the merchandising point, the lines of abutment between the rectangular panel 19 with the edges 23 of the triangular end panels 21 are preferably left unsealed. some circumstances, it may be desirable to provide a seal, such as for ex- When setting up the s all of thersides of 'the formed wedge.

When 'filling the envelopes 9, they are inserted into :the cmold'cavities r10 with fthe open ends of :theenvelopes, indicated :as 27 in Fig. 5, extending above the :edges of the :mold 11 a wsufiicient' distance to provide overlapping portions with "which the open ends of the envelopes :are sealed. After the liner 7 and envelopes '9 are assembled, as shownin :Fig. 4, the entire assemblage is placed intheshipping carton 14 while the'cheesegproductis still in :hot, fluid .form. This molds the cheese product into atrue ishape and protects 14 illustrated .is a'arectangular box 30 and side flaps 31. The carton 14 is of such dimensions that two superposed, wedgeshaped, filled liners 7 will produce a rectangular shape fit snugly within "the carton .14. The snug fit between the filled liners :andthe enclosing box insure that .the walls of the carton will produce :a barrier for the fluid cheese product in athe envelope 9. Thus, the envelopes-9 will :not sag away from 1the'walls of the liners while the spread is-still in liquid form but will instead completely occupy fined =by*the carton .14, zthe :liners"7, -andithe partitions 25. The filled carton of cheese product is then cooled, thickening to produce :sharply desmooth, unmarred surfaces. It will be aapparentthat .n'o handlingiofthe individual wedges-of cheese :is required which might result in the deformation of the'wedge Torin the separation of the envelope 9 from the cooled :pro'duct.

The rigid structure is made possible by the semblage whereby said fluid cheese out danger of deforming the cheese wedges in the lower cartons.

When the carton arrives at the retail outlet, the wedges of cheese in their individual envelopes and liners are removed from the carton and the liner is unfolded to free the two wedges contained therein. 7

While the described shipping carton contains two superposed, filled liner mernbersfi, itwill :be apparent that any even number of units may be stacked to provide a rectangularblock which may be enclosed by a rectangular carton.

Various features of the invention which are believed new are set forth in theappended claims.

I claim:

1". A method of packaging cheese 'in wedge-shaped i blocks which comprises the steps of providing a trough of V-shaped cross-section, inserting a pliable envelope containing a fluid mass of .the cheese into said trough, placing the assemblage of trough, envelope, and fluid cheese in 'a-container adapted to snugly-enclose said :as-

retains the shape of said trough regardless 0f the position of said container,

and cooling .said container to thickensaid cheese.

2. A method of packaging cheese'in wedge-shaped blocks which comprises the steps of providing apair of troughs of right-triangular cross-section, heating said cheese to transform itintoa fluidmass, fillingarplurality of pliable envelopes with said fluid mass, sealing said envelopes, placing 'a pair of filledenvelopes in:each-.oi said troughs while said cheese is stillunhardened, superposingsaid pair of assemblagesof trough-envelope, :and fluid cheese to provide za rectangular block, and enclosing said rectangular block in a rectangular-container;proportioned to snugly enclose :said block cheese retains the shape of said troughs regar iSSLOf tthe position of said box, and cooling saidbox to thickensaid cheese.

3. A method of blocks which comprises placing a pliable open :envelope in a supporting mold, pouring said cheese into said envelope while said cheese is in a -fiuid condition, sealing th'e open end of saidenvelope to provide .a sealed package of cheese still in relatively fiuid -form,,renioving said package from said mold, placing said ,package, while said cheese container adapted toenCl'ose-said ztroug'h and said piackage snugly, and cooling said-container to thicken said cheese.-
